PaddleSpeech is an open-source toolkit on PaddlePaddle platform for a variety of critical tasks in speech, with the state-of-art and influential models.
Speech-to-Text

Via the easy-to-use, efficient, flexible and scalable implementation, our vision is to empower both industrial application and academic research, including training, inference & testing modules, and deployment process. To be more specific, this toolkit features at:
- Fast and Light-weight: we provide high-speed and ultra-lightweight models that are convenient for industrial deployment.
- Rule-based Chinese frontend: our frontend contains Text Normalization and Grapheme-to-Phoneme (G2P, including Polyphone and Tone Sandhi). Moreover, we use self-defined linguistic rules to adapt Chinese context.
- Varieties of Functions that Vitalize both Industrial and Academia:
- Implementation of critical audio tasks: this toolkit contains audio functions like Speech Translation, Automatic Speech Recognition, Text-to-Speech Synthesis, Voice Cloning, etc.
- Integration of mainstream models and datasets: the toolkit implements modules that participate in the whole pipeline of the speech tasks, and uses mainstream datasets like LibriSpeech, LJSpeech, AIShell, CSMSC, etc. See also model list for more details.
- Cascaded models application: as an extension of the application of traditional audio tasks, we combine the workflows of aforementioned tasks with other fields like Natural language processing (NLP), like Punctuation Restoration.
Installation
The base environment in this page is
- Ubuntu 16.04
- python>=3.7
- paddlepaddle>=2.2.0
If you want to set up PaddleSpeech in other environment, please see the installation documents for all the alternatives.
Quick Start
Developers can have a try of our models with PaddleSpeech Command Line. Change --input to test your own audio/text file.
Audio Classification
paddlespeech cls --input input.wav
Automatic Speech Recognition
paddlespeech asr --lang zh --input input_16k.wav
Speech Translation (English to Chinese)
paddlespeech st --input input_16k.wav
Text-to-Speech
paddlespeech tts --input "你好，欢迎使用百度飞桨深度学习框架！" --output output.wav
If you want to try more functions like training and tuning, please see Speech-to-Text Quick Start and Text-to-Speech Quick Start.

Tutorials
Normally, Speech SoTA, Audio SoTA and Music SoTA give you an overview of the hot academic topics in the related area. To focus on the tasks in PaddleSpeech, you will find the following guidelines are helpful to grasp the core ideas.
- Overview
- Quick Start
- Speech-to-Text
- Text-to-Speech
- Released Models
The TTS module is originally called Parakeet, and now merged with DeepSpeech. If you are interested in academic research about this function, please see TTS research overview. Also, this document is a good guideline for the pipeline components.
